Q: Question: Who wrote the final issue of Aquaman? Passage:He was spun off into his own title, the 1968–74 series Sub-Mariner. The super-villain Tiger Shark was introduced in issue #5 by writer Roy Thomas and artist John Buscema and the super-hero Stingray in issue #19 by Thomas and Bill Everett. Some of the later issues of this Sub-Mariner series are notable for having been written and drawn by the character's creator, Bill Everett, shortly before his death; as well, they reintroduced a now-older Namora, and introduced her daughter, Namorita Prentiss. By now more of a reluctant superhero "the Sub-Mariner was perfect for the Marvel Age of angst-ridden protagonists. Noble yet misunderstood, powerful yet thwarted ... [he was] portrayed as a regal monarch – a king without a country." The final issue, #72 (Sept. 1974), was written by Steve Skeates and featured an unofficial intercompany crossover with the last issue of DC Comics' Aquaman series. A five- to six-page backup feature, "Tales of Atlantis", chronicling the undersea kingdom from its ancient origins, appeared in issues #62–66 (June–Oct. 1973), written by Gerber, with penciling by Howard Chaykin and later Jim Mooney. After the cancellation of Sub-Mariner, Namor co-starred with Doctor Doom in the Super-Villain Team-Up series. The series suffered from mediocre sales due to its lack of a stable creative team, and following issue #13 Namor was dropped from the co-star spot.
